Tim,

There was too much confusion with it due to the overlap in lift heights on the 2 different track bars. So we redesigned it to work with 3-8”, at under 3” of lift you can usually drill a new hole on the axle mount.

Thank You,

Now if and when I regear from 3.55s to 4.10s will I lose or gain gas mileage? Lose or gain speed?

 

More info needed. Tire size? Load? Engine? Terrain? Nerve damage to right foot?

This question is answered almost every day in Modified Tech.

 

31s, 3.55, 4.0l, highway driving, light foot

 

You may actually see an overall decrease in economy then. For a really light load at sustained speeds the shallower the gears the better. In city driving or hilly terrain the story is different. If you're weighed down though you'd see an improvement as it would take less skinny pedal.

Honestly I wouldn't bother regearing for 31s. Especially if you're installing gears and weren't just swapping axles that you got for cheap. If you plan on going to 33s or towing a lot it's a good idea.

 

Hay sooo I have a 95 jeep grand cherokee oand I've got a leak I believe in my rear main seal and I don't want to take it to a garage to fix it. I've also got some questions on lift kits and stuff cause Im trying to go offroading and I was hoping for some tips on how to drive it properly offroad etc. If amyone wants to help email me at hartcalvin27@gmail.com

 

You will loose speed.
From my experience, I gained mileage cause RPM is closer to ideal power band. (34" tires)

 

Wow. Too much confusion? That's weak as hell. Can't believe they said to redrill the hole. Lol

 

So what's the best way to gain power and gas mileage? A free flowing exhaust and bored throttle body?

 

Apparently answering emails or putting clarification on their web page is too expensive to justify the extra sales? Then again maybe they just never sold any of the smaller ones.

 

Thats about it unless you do an engine swap. A 4.0 can't do both lol.

Put a tranny cooler on it and drive it

 

I'm guessing the second one.

Really blows because I'm stuck with one option: JKS. There's no double shear solution for 1-2.5" of lift. Lame.

 

X2 even with 33s and 3:55s my xj had plenty of pep left.

Yeah, that surprised me lol

I'm guessing they didn't sell enough. I was waiting to lift before I bought one for the MJ.

 

Rotors from an 89 fit on a 98? How about front axle shafts? Steering wheel? How do I know what axles are in each of them?
